Abstract (en)
[origin: WO9803219A2] An endoscopic catheter distal end position control that enables precise control of distal catheter sheath ends relative to each other while accommodating the long length and flexibility of typical catheters and proximal, remote hand-operable control mechanisms. In a catheter assembly employing this control, an elongated flexible tubular sheath is provided having a distal end and a proximal end. A distal end member is internal to the sheath; this end member is reciprocally axially moveable relative to the sheath distal end between a retracted position that is proximal of the sheath distal end and an extended position in which the end member protrudes beyond the sheath distal end. An elongated end member interconnector is provided, with a distal end of the interconnector being connected to the end member and a proximal end of the interconnector being connected to a position actuator for axially reciprocating the end member relative to the distal end of the sheath. A distal end position controller is located at a point along the sheath to cooperate with the interconnector in limiting the extent of axial retraction of the end member relative to the sheath distal end. A flow channel that extends axially through the end position controller is internal to the sheath and external to the interconnector.
